Title:

HEAT EXCHANGER

Document Type and Number:

WIPO Patent Application WO/2004/109210

Kind Code:

A1

Abstract:

A heat exchanger capable of reducing a weight, improving a recyclability, and increasing a sealability of an air passage without using adhesive agent, wherein heat exchanger plates (A) and (B) formed by integrally forming, by the vacuum molding of a polystyrene sheet, heat transfer surfaces, air passage ribs, air passage end faces, grooves (A), projections, outer peripheral ribs (A), outer peripheral ribs (B), an air passage end face cover, and grooves (B) are alternately stacked on each other, the grooves (A) come into close contact with the grooves (B), the upper surfaces of the outer peripheral ribs (A) and the outer peripheral ribs (B) come into close contact with the heat exchanger plates, the projections come into close contact with the outer peripheral ribs (B) and the grooves (B), the air passage end faces are allowed to abut on the outer peripheral ribs (B), the air passage end face cover is allowed to abut on the end faces of the outer peripheral ribs (A) and the outer peripheral ribs (B), and the side faces of the outer peripheral ribs (A) are allowed to abut on each other.
